Abstract
Abstract A device for the application of liquids, particularly high viscosity substances, such as glue and the like, comprises a layon member which is inflatable and which is connected to a filling and discharge line for causing the inflation. The device may be used to fill cracks or grooves by placing the lay-on member in the groove or crack and then inflating it. The lay-on member may also include an inner core within the envelope defining a space between the lay-on member and the core for containing the medium to be applied and which will issue from the pores of the member after the lay-on member is inflated.

Claim 1
Independent Claim
99 words
A device for the application of liquids, particularly highly viscous liquids such as glue and the like, on workpiece faces, comprising an inflatable elastic bag forming a lay-on member having a surface for containing and transferring the liquid to be applied and a fitting connected to said bag for filling and discharging an inflation medium into and out of said bag, a core member extending into said lay-on member and sealingly engaged at its periphery with said lay-on member, said fitting having a flow channel connection into said core into the space between said core and said lay-on member.
Claim 2
Independent Claim
99 words
A device for the application of liquids, particularly highly viscous liquids such as glue and the like, on workpiece faces, comprising an inflatable elastic bag forming a lay-on member having a surface for containing and transferring the liquid to be applied and a fitting connected to said bag for filling and discharging an inflation medium into and out of said bag, a core member extending into said lay-on member and sealingly engaged at its periphery with said lay-on member, said fitting having a flow channel connection into said core into the space between said core and said lay-on member.
Claim 3
Dependent Claim
55 words
A device according to claim 1, wherein said lay-on member and said core are of pocket shaped configuration, said lay-on member extending into closely spaced relationship with the interior end of said lay-on member, said core having a passage extending therethrough for the inflation liquid terminating closely spaced to the interior of said lay-on member.
Claim 4
Dependent Claim
22 words
A device according to claim 2, wherein said core includes at least a portion which is rigid and forms a positioning sword.
Claim 5
Dependent Claim
22 words
A device according to claim 2, wherein said core includes a rigid portion forming a pin-like member for positioning the lay-on member.
Claim 6
Independent Claim
123 words
A device for the application of liquids. particularly highly viscous liquids such as glue and the like, on workpiece faces, comprising an inflatable elastic bag forming a lay-on member having a surface for containing and transferring the liquid to be applied and a fitting connected to said bag for filling and discharging an inflation medium into and out of said bag, a core extending into said lay-on member and having exterior walls spaced slightly from said lay-on member interior walls, said fitting providing means engageable with said core and said lay-on member and sealing them peripherally, and relief valve means for relieving the space between said core and said lay-on member to relieve the iNflation pressure therefrom if it exceeds a predetermined value.
Claim 7
Independent Claim
123 words
A device for the application of liquids. particularly highly viscous liquids such as glue and the like, on workpiece faces, comprising an inflatable elastic bag forming a lay-on member having a surface for containing and transferring the liquid to be applied and a fitting connected to said bag for filling and discharging an inflation medium into and out of said bag, a core extending into said lay-on member and having exterior walls spaced slightly from said lay-on member interior walls, said fitting providing means engageable with said core and said lay-on member and sealing them peripherally, and relief valve means for relieving the space between said core and said lay-on member to relieve the iNflation pressure therefrom if it exceeds a predetermined value.
Claim 8
Dependent Claim
47 words
A device according to claim 5 including means connecting into the space between the core in said lay-on member for filling said space with the material to be applied, said lay-on member having at least one core for the expulsion of the material to be applied therethrough.
Claim 9
Dependent Claim
25 words
A device according to claim 6 including valve means for closing the entrance to the space between said core and said lay-on member after filling.
Claim 10
Dependent Claim
106 words
A device according to claim 1 including a core member with at least a handle portion of substantially rigid form located within said lay-on member and holding said lay-on member in an extended position, said fitting including a connection extending through said core member into the space between said core member and said lay-on member to inflate said lay-on member and means for also supplying the material to be applied to the space between said core and said lay-on member, said lay-on member having a plurality of openings therethrough for the exit of the material under the pressure of the inflation medium delivered through said fitting.
Claim 11
Independent Claim
79 words
